About The Project

On deployment inject API keys authorized to use your service. Every call to a private endpoint of your service has to include a header['x-api-key'] attribute that is validated against the API keys in your environment. If it is present, a request is authorized. If it is not FastAPI return 401 Unauthorized. Use this either as a middleware, or as Dependency.
